3 Claims. (Cl. 29-89) This invention relates to work holding device, andmore particularly deals with a novel device adapted to hold automobilefenders and the like in divers positions to facilitate work thereon.

It is well known that fenders or mudguards, radiator shells, enginehoods and other parts of automobile bodies are often bent out of shapedue to collision or other accidents, and hitherto it has been diicult torepair them. On the one hand, if repairs were made without removing thedamaged part from the body, the work often did not prove satisfactory;and on the other hand, if the part was removed from the body in order torepair it, it was difficult to handle and maintain in proper position,with the result that it took an unreasonably long time to make repairsand a helper was generally needed to hold the work in position.

My improved device .enables the mechanic to do better and faster workand makes unnecessary the use of a helper to assist in holding the workin proper position. These and other objects of my invention, as willappear hereinafter, result from the novel details of construction andarrangement of parts described and illustrated in the followingspecication and annexed drawings, in which- Fig. 1 is a frontelevational view of my work holding device;

Fig. 2 is a front elevational View of the central adjustable workholding means thereof;

Fig. 3 is a cross sectional view along line 3-3 of Fig. 2;

Fig. 4 is a sectional view along line 4-4 of Fig. 1;

Fig. 5 is a front elevational view of the adjustable work holding meansat either end of my work holding device;

Fig. 6 is a side elevational View of one of the adjustable arms of thework holding means of Fig. 5;

Fig. 7 is a side elevational View along line 'i-'I of Fig. 1.

Referring now to the drawings, and particularly to Fig. 1, I is a basesupporting a member II telescopically associated with a tubular memberI2, which associated members are held positioned with respect to eachother by bolt I3 and are adapted to increase or decrease the heightofthe work holding device.

Tubular member I2 is associated at its upper end with a forked member I4and swingably positioned with relation thereto by means of bolts I andI6. As more particularly shown on Fig. 7 a segmental member I1 providedwith a plurality of apertures I8 is held in fixed relationship to forkedmember I4 by bolt I5 and adjustably positioned with respect to tubularmember I2 by bolt I6, thereby permitting my work holding devicehorizontally to swing over an arc of substantially by removing bolt I6,swinging member I4 to the desired angle, usingV bolt I5 as pivot andreplacing boltvIS. It will be understood that the degree ofadjustability will depend on the number of apertures I8 on the segmentalmember I'I (the greater the number, the finer the adjustment) and that astill greater degree of adjustability may be obtained.

f' moving bolt 23, swingingv member 22 to the desired angle using bolt2| as pivot, and replacing bolt 23. It will be understood, of course,that the degree of adjustability permitted by segmental member ISdepends on the same factors hereinbefore stated with respect tosegmental member Il. v

Tubular member 22 has attached at right angle thereto (as by welding) ahorizontally dis,- posed tubular member 23 having telescopicallyassociated therewith a member 24, which associated members are heldpositioned with respect to each other by bolt 25, said member 24 beingprovided with hanger 26 and bolt 2l, said bolt 2l serving as pivot formember 28.

Member 24 is -also provided near its free end with a slotted member 29adjustably mounted on said member 24 by bolt 30 and segmental member 3I.Member 29 is provided at its upper end with a segmental member 32 heldpositioned with respect to member 29 by pivot 33 and bolt 34, saidmember 32 being horizontally swingable with respect to the axis ofmember 29 over an arc of substantially 180 described by slot 35.

segmental member 32 carries a plurality of mem- Y bers 36 adjustablymounted thereon as will be more fully described hereinafter whenreferring to Fig. 5.

Tubular member 23 has attached at right angle thereto a horizontallydisposed member 3l (see Fig. 4) having telescopically associatedtherewith l tached'` to member 48 by. bolt Gil.

and being held adjustably positioned with respect l to member 44 by bolt47. Members 44 and 45 are adapted to co-act in association with pivoti6-and bolt 4l for the purpose of gripping and holding the edge of amudguard or the like being held positioned for the purpose ofWorkingon'it.

Referring again to Fig. 1, member 22 has attached thereto (as by weldingor screwing) an elbow 4.8A provided with a horizontally disposed member4s. Said member 4,9 is provided near its free end with a slotted member25, adjustably mounted thereon by a bolt and segmental member 3 l Member29, is provided at its upper end'wth a segmental member 32 heldpositioned with respect to. member 29 by pivot 33' a-nd bolt 3d','said,member 32 being horizontally swingable with respect to the axis ofmember 29." over an arc of substantially 185).o described by slot 3 5.segmental member 32' carries a plurality ot members 36. adjustablymounted thereon as will be more fully ydescribed hereinafter whenreferring to Fig. 5. i

It will be readily understood, of course, that elements 29.', 3d', 3i',31', 33', 34', 35." and.3.6, are substantial duplicatesv of elements 29,30, El, 32, 33, 34, and .'ihereinbefore described.

Referring new toV Fig. 5, slot 48. is adapted for longitudinaladjustment of. member E-Sby means of bolt 3rd. Slot V4l1is. adapted topermit member 32 horizontally to. swing Ywith respect to the axisof-member 2,9. Slot is adapted to permit member. 3,6 horizontally tovswing with respect tothe axis thereof. Bolt.` 34 is adapted to holdmember 31. in adjustableI relationship with member 2.9; Bolt 5l. is.adapted to hold member 36 in adjusts able` relationship. with member 32.Slot 52 is adapted for. longitudinal adjustment of member 35, and bolt53 isadapted toA hold the desiredlposi.- tion. Pivot 54 is for thepurpose of holding. mem.- ber \3.3 in swingable relationship. withmember 32. Angle, 5.5. isr provided with a slot 55. andL bolt4 51:adaptedV to regulate its position` longitudinally, and isalsoprovidedwith an aperture. 5.8!through which. is passedA a bolt, (notshown) adapted to engage theA tapped` edge. of a mudguard or. thelikefor the purpose of'securely bolting it in place, so that it may bepositioned while beingrepaired;

Referring again to. Fig, 1, 59 isa platform at- Adjustably mounted onsaid platform is a frame 6|` held thereon by bolt 52.

Referring now to-Fig. 2, d3 are a plurality of pivot supports on whichare mounted pivots 64. Pivoted thereonare a pluralityvofY tubularmembers. 65 telescopioally associated with members 6B, said associatedmembers being adjustably positioned with respect to each other by. bolt6.1.

Frame` di. is provided with stops 63. adapted to limit the horizontalmovement of members within the limits shown in broken lines. Members GSareprovded with angle heads B9, said angle heads. having slots 'lill andbolts 'H adapted to regulate its position longitudinally, said headsalso bei-ng provided with apertures 12 adapted to engage the tapped edgeof a mudguard or the like for the purpose of securely bolting it inplace, so that it may be positioned while being repaired. Theconstruction and arrangement of parts of these pivoted adjustableelements is more particularly shown in Fig. 3.

Referring again to Fig. 1, member 28 is provided with an adjustablegripping head 13 substantially as shown on member 42 in Fig. 4, and itsshank is provided with a plurality of apertures 'F4 for the purpose ofadjusting its length. This member serves the purpose of gripping anuntapped edge of a mudguard or the like for the purpose of bracing itand thereby permits proper positioning thereof while undergoing repairs.

As will be readily understood from the foregoing description and annexeddrawings, the work holding device of my 1nvention is characterized byextreme flexibility of adjustment, and is thereby a valuable tool easilyarranged for work and nevertheless olf, simple construction. Inoperation, the supporting members having tapped heads are bolted to thetapped (body) edge of the mudguard, for instance, and those havingclawlike heads, are used: to grip the untrapped (outer) edge. Members l1and i9, because of the unie versal; adjustment they permit, make itpossible for the mechanicoj` operator to. position the work in the mostfavorable manner to, carry out the repairs. i

It will be understood that my invention lends itself to variousmodications within the scope thereof. I have described and illustrated`preferred embodiments of my invention, but it should be understoodthat Ido not. intend to restrict myself to the particular details of'construction and arrangement of parts herein described and illustratedexcept as limited by the scope of the appended claims.
